An observational study in Surgery and Individuality, sponsored by Huazhong University of Science and Technology. Completed at 1 site in China. Open to female participants aged 20 Years to 65 Years. Per ClinicalTrials.gov, last updated 2016-03-22.
Sponsored by Huazhong University of Science and Technology · Observational
This study aimed to find a quick and timely way to predict the individual variation of efficacy of opioid analgesic during the operation and postoperative analgesia in Chinese patients undergoing elective surgeries. Methods: female patients receiving elective surgery under general anesthesia were recruited into this study. At the time of routine intravenous anesthetic induction we observe the efficacy of opioid analgesic including analgesic effect, effects on Narcotrend index, sedative effect, effects on respiratory system, and aslo effects on cardiovascular system. Then we record the consumption of of opioid analgesic during the operation and postoperative analgesia. Also we record the side effect of the opioid analgesic.
Patients with the following diseases were excluded: known history of chronic pain, psychiatric diseases or communication disorders, diabetes mellitus, severe cardiovascular diseases, kidney or liver diseases with poor hepatic function, alcohol or drug abuse, heavy smoker, pregnancy or at the lactation period.
Huazhong University of Science and Technology is the lead sponsor of 241 studies on the registry; 60 are open to participants now.
